The dog shows no sign of pain, the head carriage is normal, no light sensitivity, and no heavy exercise. He is an English Labrador retriever, weighing about 95 lbs. I have been out of town the last two weekends, and he had been overnighting at his favorite daycare. I do know they have small pools, and much activity all day long. The surface is also concrete. Usually he goes to day care once every two weeks, other days he comes with me to the barn where he plays with two other labs, and I will trail ride my horse with the three following me.
Since I have had him, I have always cleaned his ears every Sunday, he has never had an ear problem. Unfortunately, being gone the last 2 Sundays, I assumed that my huisband had been treating the ears, he had not. This past week I noticed the dog showed no interest in playing, retrieving etc. I also cleaned his ears and discovered that there was the brown substance in the inner ear, but no odor and discharge. Today, I had the feeling he lost his hearing, and he is reluctant to go up steps, he never really enjoyed steps, but now he would prefer to avoid them.
I made up an ear solution from a recipe of a dog owner which contains vinegar, boric acid, alcohol and betadine antiseptic solution. I have just started using it, as the store bought solution, (aloe based) had run out.
